P THOMSEN. CONNECTING MEMBER FOR SUPEEHEATER ELEMENT ENDS.

A TTOH/VEVS EDI 33 Lv Specificatio into the three holes 15. Here one connector piece is used for the saturated steam ends and a separate connector piece for the superheated steam' ends.

In the form shown in Figs. 6-8, also each set of ends of three superheater elements has its own 'connector'piece. Bolt holes 17 for attachment to the steam collector are at opposite ends, instead of bein in the center as in Figs. 1-3. The three element ends, 16, enter centrall disposed holes 15 bored from the un erside which holes connect with a single central hole bored in the upper side and adapted to register with a corre sponding hole in the steam collector. In the specific construction here shown the hole which is bored fromthe top to receive the pipe connection 13 is enlarged somewhat between the planes which bound the bottom of pipe 13 and the tops of pipes 16, as shown 111 1g. 7, as otherwise the two laterally disposed pipes 16 would have no outlet throu h to pipe 13. This, enlargement should e sufiicient to insure an opening between each lateral pipe 16 and the central pipe 13 at least as great in section as the section of saidpipe 16 so as not to restrict the flow of steam form ere shown the area 18 represents the amount by which the hole for pipe 13 has been enlarged between the planes referred to.

It will be noted that in my improved connector piece not only are the holes bored from opposite sides so as to communicate with one another, but said oppositely bored holes extend in each case nearly to the side of the connector piece opposite to that from which they started. The pipe ends 8, 9, 16 and the tube sections 13, being extended only for a short distance from the side at which they enter, there is, therefore, a lateral opening of the element end holes into the collector hole such that, the section of the collector hole being equal to the section of the pipe holes as explained, there is no constriction of the steam flow anywhere between the superheater elements and the collector chambers.

- Other modified forms of my invention may be made Within the spirit thereof. It should be noted that the connecting member of my invention may be made from solid material always to be found upon the open market and that the manufacturing operations necessary are of the simplest mechanical character e. 9., drilling, boring, reaming, etc. In some modifications turn-- ing, milling or planing operations may be helpful. Nhilc, as I have stated, I have intended my improved. connecting member more especially for connecting superheater elements to steam collectors or headers therefor, the same is, nevertheless, equally applicable to many other types and kinds of apparatus where fluids are to be carried as for example, to feed Water heaters, steam heating apparatus, steam generating and distributing apparatus generally, and the like and the scope of the claims which follow is to be taken including such apparatus. I

Having described my invention, I claim 1-- 1. A connecting member for joining a plurality of pipes to a single pipe, comprising a solid block having holes bored from one side to receive the plurality of pipes, and a hole bored from the other side, inter- I secting each of the first named holes, to refrom 1pc 16 to pipe 13. In the particular ceive the single pipe the cross section of the bore for the single tube being substantially equal to the combined cross. section of the plurality of pipes.

2. A connecting member for joining a plurality of pipes to a single pipe, comprising a solid block having holes bored from one side to receiye the plurality of pipes, and a hole bored from the other side, intersecting each of the first named holes, to receive the single pipe the cross section of the bore for the single tube being substantially equal to the combined cross section of the plurality of pipes, the smaller holesand the singlelarger hole being both extended past the central plane of the block.

In testimony whereof, I have hereunto set my hand in the presence of two subscribing' witnesses.
